Functions ¶
func CRT ¶
CRT is a function that takes a slice of cycles and returns the smallest number that satisfies all the cycles according to the Chinese Remainder Theorem.
func ContainsInt ¶
func ContainsString ¶
func CountStrings ¶
func FirstAsciiNr ¶
FirstAsciiNr return ascii number of first character in string. Panics if value > 127.
func MinMaxInts ¶
func ReadLinesFromFile ¶
ReadLinesFromFile reads lines from a file.
func ReadNumbersFromFile ¶
ReadNumbersFromFile reads one integer from each line in file.
func ReadRawLinesFromFile ¶
ReadRawLinesFromFile reads lines from a file.
func ReverseSlice ¶
func ReverseSlice[T any](s []T)
func SplitToInts ¶
SplitToInts finds all ints in line (including sign).
func SplitWithSpace ¶
SplitWithSpace splits a line with space as separator.
func SplitWithTrim ¶
func TrimTrailingNewline ¶
TrimTrailingNewline removes trailing newline
Types ¶
type Command ¶
func ParseCommand ¶
ParseCommand parses a "verb value" from a line.
type Cycle ¶
type Cycle struct {
Offset, Period int
}
Cycle is a struct that represents a cycle with an offset and a period.
type Grid2D ¶
type Grid2D[T comparable] struct { Grid [][]T Width int Height int }
func CreateGrid2D ¶
func CreateGrid2D[T comparable](width, height int) Grid2D[T]
type RuneGrid ¶
func CreateRuneGridFromLines ¶
type Set ¶
type Set[K comparable] map[K]struct{}
Set - mathematical set with operations Empty struct requires zero bytes so is more efficient than bool
func (Set[K]) Remove ¶
func (s Set[K]) Remove(elem K)
Remove - remove elem from set (does not need to be in set)
